عَنْ عَامِرِ بْنِ رَبِيعَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَخْطُبُ يَقُولُ مَنْ صَلَّى عَلَيَّ صَلَاةً لَمْ تَزَلِ الْمَلَائِكَةُ تُصَلِّي عَلَيْهِ مَا صَلَّى عَلَيَّ فَلْيُقِلَّ عَبْدٌ مِنْ ذَلِكَ أَوْ لِيُكْثِرْ
It is narrated from Sayyiduna Amir bin Rabi’ah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said while addressing: Whoever sends blessings upon me, the angels continue to pray for mercy for him as long as he keeps sending blessings upon me. Now it is up to the servant whether he does so little or much.
